Can we convert a line into slices of words?

[monsterlegend99 (Monster)]

Hello, as we know golang doesn’t support long Linux commands like service httpd restart
we have to run it via exec.Command(“service”,“https”,“restart”).Output()

What am thinking is to create an function called shell_exec() which takes an string argument and convert it to slices by space and we can run the command via exec.Command
Like shell_exec("service httpd restart")
then shell_exec function will convert sercice httpd restart to three different words service httpd restart
and then we can able to send these words to exec.Command().Output()

Anyone have any idea ?

Hi there,
you can use strings.Split function https://golang.org/pkg/strings/#Split
e.g.:

// command - a parameter of shell_exec
args := strings.Split(command, " ")
exec.Command(args...).Output()

In VS Code , at ... i’m getting this error - can only use ... with matching parameter compiler
and when using go build , i’m getting this error :

# command-line-arguments
./gocmd.go:14:27: not enough arguments in call to exec.Command
        have ([]string...)
        want (string, ...string)

To match the function signature, it needs to be written as

exec.Command(args[0], args[1:]...)
